有害水壶

一位亲戚很认真的告诉我们,其实我们每天用来装水带出门的水壶很多都是不符合标准的,它们容易让水变质,常喝会对人体有害。大多数容器底部都印有号码,这些号码是质料的分类。

我最记得他说过:-

1号》 只可使用一次

245号》 都可以安全每天使用

我回家检查了特地买来用的新水壶(因为害怕每天用《1号》矿泉水瓶会伤身),竟然发现新水壶是《7号》!糟糕!竟然比之前的《1号》更糟!呜……浪费钱了!后来发现到市场上的水壶,很多都是《7号》的,没看到有245号的水壶,叫我怎么办?究竟这说法正确的吗?

从网上找到以下资料,又没清楚说明可否安全每天当水壶使用。

Types Of Plastic

In the United States, the following codes represent the seven categories of plastic used in nearly all plastic containers and product packaging:

1 - PET

PET or PETE (polyethylene terephthalate) is a clear, tough polymer with exceptional gas and moisture barrier properties. PET's ability to contain carbon dioxide (carbonation) makes it ideal for use in soft drink bottles.

Examples: Soft drink bottles, detergent bottles

2 - HDPE

HDPE (high density polyethylene) is used in milk, juice and water containers in order to take advantage of its excellent protective barrier properties. Its chemical resistance properties also make it well suited for items such as containers for household chemicals and detergents. Most five gallon food buckets are made from HDPE.

Examples: Milk bottles, shopping bags

3 - V

Vinyl (polyvinyl chloride, or PVC) provides excellent clarity, puncture resistance and cling. As a film, vinyl can breathe just the right amount, making it ideal for packaging fresh meats that require oxygen to ensure a bright red surface while maintaining an acceptable shelf life.

Examples: Plastic food wrap, shrink wrap, garden hoses, shoe soles

4 - LDPE

LDPE (low density polyethylene) offers clarity and flexibility. It is used to make bottles that require flexibility. To take advantage of its strength and toughness in film form, it is used to produce grocery bags and garbage bags, shrink and stretch film, and coating for milk cartons.

Examples: Squeeze bottles, dry cleaning bags

5 - PP

PP (polypropylene) has high tensile strength, making it ideal for use in caps and lids that have to hold tightly on to threaded openings. Because of its high melting point, polypropylene can be hot-filled with products designed to cool in bottles, including ketchup and syrup. It is also used for products that need to be incubated, such as yogurt. Many Cambo, Tupperware and Rubbermaid food storage containers are made from PP.

Examples: Bottle caps, take-out food containers, drinking straws

6 - PS

PS (polystyrene), in its crystalline form, is a colorless plastic that can be clear and hard. It can also be foamed to provide exceptional insulation properties. Foamed or expanded polystyrene (EPS) is used for products such as meat trays, egg cartons and coffee cups. It is also used for packaging and protecting appliances, electronics and other sensitive products.

Examples: Plastic foam, packing peanuts, coat hangers

7 - Other

Other denotes plastics made from other types of resin or from several resins mixed together. These usually cannot be recycled.

以前以为7号是最好的,哪知道7号是最差的!

sock peng,

那个号码通常在底部,以箭头围成三角形的标志,中间有一个数字。
Tupperware牌子蛮出名,可能会比较专业吧!
可惜它没注明采用什么质料,不知该放心使用吗?>_<'



Kikey Loo,

我也这么认为,以为号码越大就品质越好!
可是市面上很多‘太空瓶’都是<7号>呢!
我还以为太空瓶最合用呢!

你让人又羡慕又佩服,年纪轻轻就很懂得生活,
可惜我已经过时了……

我只知道放在车上晒到热的水不能喝。

还刮到花了
怎么办?

梦想罐头 said...

圣诞节愉快

其实很多时候是"明知道"不好,但还是"沒办法",因为方便嘛,管它7号还是8号!

一旧饭 said...

我用tupperware哦, 用咗几年未死, 应该冇事啩...

龍貓 said...

我也搞不情楚

冬至快樂

Ashley said...

键轩惠馆,

对呀!晒过的水会产生化学作用而对人体有害的,
我每次都不管,等水冷了再喝……
要改了,不再喝了。



oms,

怎么办?最好的办就是换掉咯!
刮花了可能更容易产生化学作用呢!
快去找个新的吧!



梦想罐头,

哈!家里应该有很多水壶给你检查吧!
若要换的话,还得买好几个了,
今年圣诞就统统送水壶咯!^^
圣诞快乐!:)



薰衣草夫人,

你说中很多人的心啊!我就是其中一个了 >_<'
问题是还没看到可安全使用的<2>、<4>、<5>号啊!
不是我不买啊!现在只好还用着<7>号!



一旧饭,

tupperware好像没写是什么号码哦?
这牌子好像很专业,奇怪是没放号码。
有句话叫‘慢性自杀’啊!>_<'



龙猫,

冬至快乐!圣诞快乐!
昨晚吃了很多、很多东西,所谓病从口入,真的要好好搞清楚自己的身体啊!

papa &mama said...

哎哟!我们只要能装得进水又没什么特别味道的都用,几十年了哦.

Ashley said...

papa &mama,

听说以前的人比较‘tahan',现在的人很’化学‘了!
以前水喉水、河水照喝,现在的人要喝什么过滤水、能量水!>_<'

7号啊!就是说不能再循环咯~很不环保咯~但又没法子啦~

janelle_l said...

我那时候也是傻傻跑去买7号的。。结果现在说不能用,看来要去买一个铁的才行了。。

Ashley said...

疯侠 Chaos,

欢迎来到双子城堡! ^^
是咯!是咯!好像很多人都在用7号哦!
是无良商家做出来的,好像找不到2、4或5号哦!



janelle,

铁的?有吗?是那种可保温的吗?
我上次有买过一个,才用过几次就生锈了!
看来还是没有办法了 >_<'

使用不銹鋼的,加上勤加清洗就行了。

堕天使-祥,

看来,你是很勤力做家务的男人哦!
不然,就身边有一位很勤力为你做家务的人!
